When Christoph Kaiser came across this unused 1950s grain silo belonging to a farmer in Kansas he immediately had the idea to transform the unusual space into a home for him and his wife. The end result is not only stunning but also eco-friendly.

Inside, Kaiser crafted a curved interior that matches the silo's circular footprint. "I didn’t want to cheat and do a box inside a curved shell," he says. "I wanted it to feel like the inside and outside were born of the same mentality." Scrap walnut plank flooring purchased on Craigslist for $350 accounted for most of the interior wood. It's paired with black steel touches. Everything in this room is custom—Kaiser designed the curved-faced cabinets, the dining table, the sofa, and the lamp that has hooks for pots and pans. The countertops are Corian. The Eames Wire Chairs are one of the only non-custom elements.
